GAR-COUPLING ANCHORAGE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed July 28, 1917. Serial No. 183,315.

a coupler anchorage which will yield to,

abnormal strains due to breaks in the grade and thus lessen the danger of breaking parts of the coupler or rendering same inoperative.

Another object of my invention is to provide a coupler anchorage which will permit of lateral movement of the coupler head and which is strong, durable and can be con structed at a reasonable cost.

Another object of the invention is to provide a coupler anchorage which will permit coupled cars to pass over extreme vertical curve in the tracks.

A further object of my invention is to provide a pivotal connection for supporting one end of a coupler, the connection being vertically movable when subjected to abnormal vertical strains and which under normal conditions is held stationary in a predetermined relation of the parts. I

attain these and other objects by the mechanism illustrated in the following drawings in which: i

Figure 1 is a sectional view of a coupler anchorage embodying my improvements.

Fig. 2 is a plan view of the device.

Fig. 3 is a cross-sectional view of a modified form of the invention.

Fig. 4 is a plan view of the device shown in Fig. 3.

The same reference characters represent the same parts in all of the views. Reference numeral 1 indicates a housing having a flange 2 made integral therewith by means of which the housing is secured to the bottom of a car in the usual manner. The housing 1 is provided with a bearing 3, which extends into an enlarged opening 4, forming a shoulder 5. Collars 6 and 7, provided with grooves 8 and 9, which are adapted to receive the ends of the spring 10, are slidably mounted within the opening 4. The spring 10 is compressed between the collars 6 and 7, and retained within the opening 4 by means of the shoulder 5, and a retaining ring 11, which is secured to the housing by studs 12. A yoke 13, provided with a shoulder 14, adapted to engage the collar 6, and having a shank 15, is rotatably mounted in the bearing 3. The shank 15 is adapted to freely pass through the collars 6 and 7, and has a disk 16, attached to the end thereof by the bolt 17. The disk is locked against rotative movement with respect to the shank by the pin 18, and is adapted to engage the collar 7 in a manner as will be hereinafter fully described.

The lower end of the yoke 13 is bifurcated and has the eye 19, of the coupler end 20, pivotally mounted therein upon a pin 21.

A modified form of my invention is shown in Fig. 4 comprising a housing 1, having an opening 4. Mounted within the opening 4, for combined vertical and rotatable move ment is a yoke 13, which has a shoulder 14, and is provided with a shank 15. The yoke 13 has a central extending opening 22, which is adapted to receive the head 23, of a stem 24, which is secured to thehousing 1. A spring 25, is positioned between the head 23, and the end of the shank 15, which is adapted to yieldingly support the yoke 13, in its normal operative position, the spring being compressed when the yoke is moved in a downward direction due to abnormal strain. The yoke 13 is prevented from being arred or moved in an upward direction by means of the spring 10, which is mounted within the opening 4 and adapted to engage the shoulder 14, the spring 10 being compressed when the yoke is strained in a manner as to be moved upward.

It will be noted from the foregoing description that, as the yoke is being moved in an upward or downward direction, one of the springs will be actuated irrespective and independently of the other and that the yoke willbe restored to its normal position by the actuated s ring and maintained therein by the combined action of both of the springs.

Referring to Fig. 2 of the drawings it will be noted that the yoke 13 is mounted within the housing 1 by means of the collars 6 and 7 which normally maintain the yoke in a fixed relation with respect to the housing and that the arrangement of the parts is such as will permit the yoke to be vertically moved within the housing when subjected to abnormal vertical strains. F or instance, when the coupler part 20 is strained in a manner as to exert an upward pressure upon the yoke 13, sufiicient to counteract the action of the spring 10, the collar 6 will be raised from its seat, being actuated by the shoulder 14-, compressing the spring 10. Likewise, when the strains are oppositely directed or in a manner as to exerta downward pressure upon the yoke 13, :the collar 7 is moved, being actuated by the disk 16, compressing the spring :10. The yoke is automatically restored to its normal operative position by the spring when relieved from abnormal pressure or strains.

Having thus described my invention, and shown several forms of devices embodying the same, I do not wish to be limited to the details of construction shown, since these can obviously he changed without departing from the spiritand scope of the invention.

iWhat Iclaim, Ell1Cl;(lQSl1"BtO secureiby Letters Patent is:

1. A car coupler anchorage for securing one end ofacoupler to a car body consisting of a stationary part to be secured to a car body in combination with a rotatable part provided with attaching means ,to pivotally secure one end of a :coupler thereto, and

yieldable means supporting said rotatable part and tending to anaiinta'in @the same in a predetermined vertical position ainder normal strains .but yielding ,to abnormal rentical strains in eithei direction ;from1the predetermined position.

2. Ina car coupler anchorage for movably securing oneiendiof acoupler to a car body, a stationarypartto be secured toa car body, a rotatable part comprising means ;for ipivotally connecting one end of a coupler thereto, and yieldahle means engaging both of said parts andstending to maintain said rotatable part in a predetermined vertical position relatively rto said stationary part, said yieldable means normally resisting vertical movementof the rotatable part but permitting ,vertical movement thereof in either direction from the predetermined position under abnomnal rpressure.

In acoupleranchora e for securing one end of acoupler t-o a can ody a stationary part to be secured to a car body, a rotatable pa rtmounted thereinand vertically movable with respect thereto, said rotatable part comprising a portion projecting below the end of the stationary part provided with attaching means for pivotally connecting one end of a coupler thereto, and yieldable means in the stationary part and around the rotatable part and operatiively engaging the latter to maintain the same in a normal vertical position but permitting vertical movement there of in either direction from the normal position .under pressure.

l. In-acoupler anchorage [for securingone endiof a coupler to a car body, a stationary part provided with a sleeve and adapted to be secured :to a car body, a movable part mounted in the sleeve for combined rotata ole and vertical movement and provided with means disposed below the end of said stationary .part to pivot-ally attach one .end of a coupler :thereto, yieldable means in the sleeve and encircling said movable part, and cooperating surfaces between said stationary part, yieldable means and movable part tending to maintain the latter in a normal vertical position :but permitting vertical movement thereof above or below the normal position. V

5. A coupler anchorage for securing one end of a coupler :toa car body consisting of a stationary part provided with a sleeve having an inwardlyiextendingc shoulder adjacent one end thereof, a movable collar seated on the shoulder, acompression spring mounted upon the collar, another collar mounted on the top of ;the spring, .and a retaining ring secured .to the stationary part for maintaining the spring :in compression :between the collars within the sleeve, in combination with a mova le part mounted within the sleeve by engagement with saidioollars for combined rotatable and vertical movement in either direction.

6. Acoupler anchorage as in claim 5, the movable part comprising a shoulder to movably ,enga-ge one of the collars for vertical movement in one direction and means to movably engage the other collar for vertical movement in the opposite-direction.
